Classistreambuf_iterator<charT,traits>::proxy is for exposition only.
An implementation is permitted to provide equivalent functionality without providing a class with this name.
Classistreambuf_iterator<charT, traits>::proxy provides a temporary placeholder as the return value of the post-increment operator (operator++).
It keeps the character pointed to by the previous value of the iterator for some possible future access to get the character.
namespace std {template<class charT, class traits>class istreambuf_iterator<charT, traits>::proxy { // exposition only charT keep_; basic_streambuf<charT,traits>* sbuf_; proxy(charT c, basic_streambuf<charT,traits>* sbuf): keep_(c), sbuf_(sbuf) { }public: charT operator*() { return keep_; }};}
